Phylum Mollusca is one of the richest phyla in living species [1]. Within this classification is the gastropod Melanoides tuberculata (O. F. Müller, 1774), with an operculum, which protects it from environmental weather [2]. One of the limiting factors for organisms is light, altering behavior, reproductive period and distribution [3].

This study aimed to observe the effect caused to Melanoides tuberculata by different types of lamps.

Samples of Melanoides tuberculata were sampled in Rio Grande, in Água Comprida/MG. In the laboratory, samples of five animals were separated in each aquarium with an approximate volume of 800 ml. The aquariums were aerated and the physical-chemical parameters of the water. Each of the six aquariums was subjected to a different type of light, one of which was designated as a control. The other treatments were UV lamp C; Ultraviolet lamp A; Incandescent lamp; Cool white compact fluorescent lamp and Warm white compact fluorescent lamp.

The physical-chemical parameters showed variations between treatments, but these were not significant. The Incandescent Lamp seems to have favored primary production. Animal survival varied significantly between treatments. When using the parametric test for analysis of variance, comparing the means of treatments; a “p” value equal to 0.000 was obtained, indicating a probability of less than one millionth that the differences were due to chance. Treatment with the UVC lamp determined the death of all animals. On the other hand, the treatment with the highest survival rate was the treatment with a warm white compact fluorescent lamp.
